Xi is the multifunctional input terminal of X1~X6. Its corresponding terminal function shall be defined as
function No. 5 “three-wire running control”.
This function code is used to adjust the change rate of terminal UP/DOWN when setting the frequency.
The interference immunity of terminals X1~X6 can be improved by properly increasing the value of
P09.10. the longer the filtering time of the terminal is, the longer the action delay time for the terminal will
be.
 Note
When terminal X6 is used as the common digital input terminal, this filtering time (P09.10) is enabled; when
terminal X6 is used as the high-speed pulse input terminal, the filtering time is P09.14.
When the digital input terminal X6 is used as the high-speed pulse input terminal, the maximum input
pulse frequency can be determined by this function code.
This function code defines three different central point modes when terminals X6 is used as the pulse
input.
